Is it limited to two 1 terabyte drives or can you install two 2 terabyte drives?

My two WD Green 2TB drives worked until one failed. The two WD Red 4-TB drive does not work in DNS-321, failed to format and could not recognize the correct capacity in the RAID 1 configuration menu. FW is v1.03.

It will do two 2-terabyte drives. Make sure you update to the latest drivers though or it won't.

I'm not sure either. I've only used mine for 1 drive. I doubt it would work for 2 at once. You would probably need 2 adapters and some software that could reconstruct the data, which is shared between the 2 raid 0 drives.

I purchased the 2-drive version, but if the same thing applies to this as other 4-drive NAS's, you'll want to install them at least in pairs (if doing RAID 0 or 1). If you're going to want RAID 5 (and if the 4-drive unit supports it, which I assume it does), you'll want to install all 4 for best results. Edit: The 4-drive NAS's I've used only allow for 2 arrays, so don't plan on having 4 separate single-drive arrays.

If you are set on Raid 1, it will limit you to 4 TB because the other drive is duplicating #1. If you go into your WD My Cloud you can change from Raid 1 and obtain full use of the aggregate 8 TB if that is what you want.

Do a google search for that. I doubt you can mount a second hard drive in there, but I'm not sure.

Yes. I have two 2TB Elements and have never had a problem. I have a 722, 722K and 622.

Not sure why there would be a size limitation. I am using 1.5 to 3Tb SATA drives with no problems

I haven't tried it yet, but when I called the company they said that it would, but you have to use two drives with the same capacity.

The manual doesn't say. I used a 1TB drive and it worked fine. You can add 2 external drives, but no mention of size limit there. You can map it as a network drive, so you can move content back and forth that way, but slower ofc.

I started with one 2TB and have been running it for several months. Adding a second of another brand and size. It's flexible to do that. You can even put in 2.5's with a converter tray, or some people mix in SSD's as well. Pretty limitless. AND most use cases are hot swappable, meaning you can pull and add drives while running.

Each drive will always be a bit different, as no two drives will have the exactly the same free space. Mine is 931GB

Although I am using two 1TB drives in RAID 1 mode, the manual says "2 x 2.5" SATA HDD, total capacity up to 6TB".

You can configure the drive to be either 4 TB or 8 TB. The device itself only contains two 4TB drives.

Yes, when using it in that configuration, your computer will recognize it as two seperate drives.

You could use two like that but it would not be daisy chaining. There would be no connection from the first drive to the second, but the computer would see both.

It handles 2TB no issues and you can mount as 1 big drive. Suspect if you upgrade to whs2011 it can handle it. I have 2 whs and like them. Pimped them out with more ram and a faster CPU

Depends on the mobo but you should be able to fit one in, i doubt two without taking out the hdd cages
